FrontierCode cost analysis: $0.09 to $12 per task, GPT-6 models lead token efficiency
ArtificialAnlys · x · 2026-10-13
Artificial Analysis continued its FrontierCode 1.1 cost breakdown:
- Cost per task spans two orders of magnitude: $0.09 for GPT-6 Luna (max) up to $12.00 for Claude Fable 5.1 (max with fallback);
- Cost Pareto frontier: GPT-6 Luna (42% / $0.09), MiMo-V2.6-Pro (45% / $0.18), GPT-6.1 Sol (49% / $0.81), Claude Opus 5.5 (52% / $10.15);
- Token efficiency: GPT-6 Astra and GPT-6.1 Sol average just 27k / 33k output tokens per task vs. 157k for Claude Opus 5.5 and 236k for Claude Sonnet 5.5 — Anthropic's edge comes at multiples of token spend.
